Solve for d:
\n" ); document.write( " $\"18d%5E2%2B30d%2B12+=+0\"$ Factor.
\n" ); document.write( " $\"%283d%2B3%29%286d%2B4%29+=+0\"$ Apply the zero product rule: If a*b = 0, then either a = 0, or b = o, or both.
\n" ); document.write( " $\"3d%2B3+=+0\"$ or $\"6d%2B4+=+0\"$
\n" ); document.write( "If $\"3d%2B3+=+0\"$ then $\"3d+=+-3\"$ and $\"d+=+-1\"$
\n" ); document.write( "If $\"6d%2B4+=+0\"$ then $\"6d+=+-4\"$ and $\"d+=+-2%2F3\"$ \n" ); document.write( "

\n" );
